All depends on how much you have to spend and how much you expect in rent.
I live in Moreton and would like ot think I live in a nice area and I know houses are rented £600+. But then you can be looking at a £120k + to buy. Again it depends on what you are looking for!
Buy the best house that you can afford in the best area - in most instances this will involve some repair & maintenance. Prepare to part with at least a 30% deposit and don't expect the rent to cover the mortgage, when rates go up again a lot of people will find themselves having to fund this through a smaller disposable income. See what the banks have by way of repossessions.
There are some 3 bed semi detached houses in Bromborough & Eastham on the market now asking less than £150k. and from what I can tell on rightmove.co.uk most of them would rent at around £650 ish a month if you were to purchase one. Good Luck with it.
If you are not going to live in it yourself, why not buy a pub and convert into as many flats as you can for rent. Not the best of areas ,the Bidston Pub is up for sale (£190,000) click for pic
